The Seyco vac that I have is the old type.Just did not work for me. So i went back to my Fein with tool start and a Dust Deputy.If you go on amazon they have an Auto Start switch that worked great for me when I use my Shop Vac.It has some negative reviews But I used it for Planers,Router Table,Table Saw and never had a problem.just a thought.I use my fein now because it is quieter and the older model Fein that I have has 4 speed settings.so it was quieter than the seyco Vac
